Solve the following using GRFSA: G-iven, R-equired (the unknown), F-ormula, S- olution, A-nswer 1. A football player kicked a football with an initial velocity of 20 m/s. at an angle of 60 a. How long did the ball stay in the air. HINT: Assume that the ball lands at the same height as its starting position. b. What is the range of the ball? c. What is the maximum height of the ball? GIVEN: V= 20 m/s 0 = 60 Required/Unknown: t Add = ? d.= ? dy max = ? FORMULA & SOLUTION GUIDE: a. solving for t requires you to have v, first. To solve for vy, use this: Vy = V, sin Then, compute for t. using: to = After that, use the formula to compute for: t total = 2t b. Solving for d, requires V., use this formula: Va = VICOS After getting V., use:d. = v.t c. Now, solve for dym. using
